Reverse racism comments

These are the sorts of comments used:

"Some white fellas just want to be black fellas."
"We've probably all got a bit in us."
"Why can't you just be an Australian?"
"He's doing a white man's job, so he's a white man."
To be fair, such thinking is not limited to Anglo people. Similarly problematic comments have been made to me by Indigenous people of various cultural backgrounds, including,
"Look, half-caste boy there walking."
"We're smarter than them, because we got white blood in us, eh?"
"Eh! You walk in here just like you proper blackfella!"
